Display panel, method of manufacturing the display panel, electronic device, and method of manufacturing the electronic device

A method of manufacturing a display panel, the method comprising:

• forming a light-emitting diode in a display area of a substrate comprising an opening area, a middle area at least partially surrounding the opening area in plan view, and the display area at least partially surrounding the middle area in plan view;
• forming a first dam extending over the opening area and the middle area;
• forming, between the first dam and the display area, a second dam comprising a second organic part, and a second metal part in the second organic part, and having a part protruding over a side of the second organic part;
• and
• cutting the first dam and the substrate along a boundary between the opening area and the middle area.

An electronic device comprising a display panel, wherein the display panel comprises:

• a substrate comprising an opening area, a middle area at least partially surrounding the opening area in plan view, and a display area at least partially surrounding the middle area in plan view;
• a light-emitting diode in the display area;
• a first dam in the middle area, and comprising two or more selected from a first organic part, a first inorganic part, or a first metal part;
• and
• a second dam between the first dam and the display area, and comprising a second organic part, and a second metal part in the second organic part, and having a part protruding over a side of the second organic part.
